Shy Guys behave identically to Arm-Mimics, in that they mirror Link's movement in the opposite direction; when Link moves up, they move down, and when Link moves right, they move left, and vice versa. Mask-Mimics wear a protective mask on their faces, which protects them from Sword attacks. Only their backsides are vulnerable to attack. Since Link cannot face their backside as a result of the enemy mirroring his every movement, they can only be attacked by charging and releasing a Spin Attack when the hero's and enemy's backs are turned against each other. Alternately, they can also be defeated by throwing Bombs or shooting two Arrows at them. The Magic Rod and Boomerang can also be used to defeat them. Although while Arm-Mimics can be defeated by dashing into them with the Sword and Pegasus Boots, this does not work on Mask-Mimics. They appear in the Bottle Grotto and Face Shrine.
